Definitions

  • the invention concerns a dishwashing machine comprising a washing chamber where objects to be washed are contained during operation of the machine, a bottom surface forming a lower limitation of the washing chamber, a sump cup for collecting and holding washing water from the washing chamber, an arrangement for re-circulating washing water from the sump cup back into the washing chamber of the machine, and a heating element for heating re-circulating washing water.
  • Dish washing machines are commonly designed to re-circulate process/washing water during operation of the machine and are commonly equipped with a heating element for heating the re-circulating water before it re-enters the washing chamber of the machine, typically via spray arms.
  • the heating elements have been of the electric type, for instance because of their high heating capability (high heat transfer per surface area unit), which makes it possible to use relatively small heaters that can be placed in e.g. a pump house , as exemplified in e.g. EP0898928A1 .
  • Further examples of dish washing machines making use of electric heating elements are disclosed in DE19951838A1 and DE3635778A1 .
  • An object of the present invention is to provide a dishwashing machine allowing for an energy efficient heating of re-circulating water. This object is achieved by the machine defined in claim 1.
  • the invention concerns a dishwashing machine comprising a washing chamber where objects to be washed are contained during operation of the machine, a bottom surface forming a lower limitation of the washing chamber, a sump cup for collecting and holding washing water from the washing chamber, an arrangement for re-circulating washing water from the sump cup back into the washing chamber of the machine, and a heating element for heating re-circulating washing water.
  • the heating element is configured to allow through flow of a heating medium, and the heating element is arranged in the sump cup.
  • a heating element that is designed for through flow of a heating medium makes it possible to let the heating element form part of a heat exchange system that has the potential to form a more energy efficient system than when using an electrical heating element.
  • the heating medium gives off heat via the heating element to the process water collected in the sump cup.
  • a heat source for heating the heating medium can be an external heat system based on e.g. solar heat, bedrock heat or a district heating system, or a heat pump system that is more or less included in the machine. In the latter case the heating element in the sump cup forms the condenser of the heat pump.
  • the inventive way of positioning the heating element in the sump cup allows larger and thus more efficient heating element to be used compared to placement in ducts and/or in connection to the re-circulation pump because the sump cup normally provides more space, or can at least more easily be adapted to provide more space.
  • This is of particular importance for a heating element containing a flowing heating medium since such a heating element often requires a larger heat transfer surface than electrical heating elements for the same heating power (because of lower heat transfer per surface area unit).
  • the sump cup can more easily be adapted to fit a particular heating element.
  • the inventive heating element is also more cost effective than other solutions such as coaxial pipe heat exchangers.
  • the machine comprises at least one filter for filtering recirculating process water, wherein said at least one filter is arranged such that recirculating water leaving the washing chamber is filtered prior to contacting the heating element. Further, washing water is collected and held in the sump cup during operation of the machine and the heating element is thereby positioned below the water level during operation of the machine which facilitates an effective heat transfer and a reduced risk for overheating of the heating element.
  • the bottom surface of the washing chamber is provided with an opening and the sump cup is arranged below the bottom surface and in connection to the opening such as to allow washing water to flow from the washing chamber into the sump cup.
  • the washing water thus leaves the washing chamber via the opening and the sump cup.
  • the heating element is arranged to form a substantially vertical cavity with at least one open end, wherein the heating element is positioned such that the at least one open end faces the opening in the bottom surface.
  • the vertical cavity thus has an open upper end through which water can enter into the cavity.
  • the heating element can be arranged with an open bottom end and/or with radial passages so that the water can flow out from the cavity via the open ends and/or the radial openings.
  • the vertical cavity allows a filter of e.g. the common cylindrical and removable type to be fitted into the sump cup in a conventional way. The heating element will thus extend in the space delimited by the outer walls of such a filter and the inner walls of the sump cup.
  • the heating element can thus be arranged along the inner walls of the sump cup which provides for an efficient use of the space of the sump cup. Further, it makes it possible to filter the water that passes through the opening in the bottom surface before it comes in contact with the heating element. Thereby, the risk of soiling the heating element is avoided.
  • the dishwashing machine may comprise an elongated filter member configured to filter washing water that passes from the washing chamber via the opening in the bottom opening into the sump cup.
  • the filter member is adapted to be inserted through the opening in the bottom surface and be attached in a removable manner at the opening such as to at least partly protrude downwards inside the sump cup, wherein the heating element is arranged such as to circumferentially surround the filter member in the sump cup when the filter member is attached at the opening. By fitting the heating element around the filter member the space in the sump cup is efficiently used.
  • the heating element comprises a pipe that is arranged in a pattern that forms the substantially vertical cavity. Such a pipe-based design facilitates the through flow of the heating medium. A pipe is also easily adaptable to fit into the sump cup. The heating element is arranged such that washing water from the washing chamber is allowed to flow past the heating element and hence facilitate an efficient the heat transfer.
  • the pipe is arranged in a coil structure.
  • a coil structure provides for a relatively easy and cost-efficient production.
  • the coil structured pipe preferably extends circumferentially a plurality of rounds in the sump cup, preferably along the inner walls, thereby providing a large heat exchange surface such that the heat transfer between the heating medium and the water is efficient.
  • a small distance between at least some of the pipe rounds (pipe "layers") in the coil allows water to pass out in a radial direction from the cavity inside the coil.
  • the coil structure may be of cylindrical shape, conical shape or any other suitable shape forming the substantially vertical cavity.
  • the heating element forms part of a heat exchange system through which the heating medium is intended to flow and take up energy/heat via a heat source and give off energy/heat via the heating element.
  • the heat source may form part of the machine or be external. In both cases the heating element may form part of a closed system forming a closed loop through which the heating medium is intended to flow.
  • the heat exchange system may be a heat pump comprising an evaporator and a condenser, wherein the heating element forms the condenser. Normally, such a system comprises also a compressor and a release valve and forms a closed loop for the heating medium.
  • the evaporator forms the heat source for the heating medium.
  • the evaporator can form part of the machine and take its energy from e.g. the surrounding air.
  • An external heat source is suitable based on e.g. solar heat, bedrock heat or a district heating system.
  • the heating element can be connected so that water (or another heating medium) heated by such an external heat source flows through the heating element.
  • the same external heat source may used to heat e.g. room heating radiators in a building.
  • the sump cup preferably comprises at least one outlet for water to be re-circulated.
  • the re-circulation outlet is preferably arranged such as to allow a sufficient heat transfer from the heating element to the washing water before the collected washing water is passed on via the re-circulation outlet.
  • the arrangement for re-circulating washing water may comprise pump means and flow ducts connecting the sump cup and the washing chamber via the pump means.
  • the sump cup is connected to the flow ducts via the re-circulation outlet.
  • the sump cup preferably also comprises a drainage outlet arranged at the bottom of the sump cup.
  • a drainage outlet arranged at the bottom of the sump cup.
  • the heating element is made of stainless steel or a resistant plastic material. Such materials are suitable for the rough environment in the sump cup.
  • the bottom surface may be inclined downwards towards the opening such as to facilitate transport of the washing water from the washing chamber to the sump cup.
  • sum cup refers to a container for collecting and holding washing water comprising wall(s) and a bottom forming the collecting space.
  • Figures 1-5 show an embodiment of the inventive dishwashing machine (1) comprising a heating element (5) arranged in the sump cup (4) of the dishwashing machine (1).
  • FIG 1 shows a front loaded dishwashing machine 1 comprising a washing chamber 2 where objects to be washed are contained during operation of the machine 1.
  • a front door of the dishwashing machine is omitted from figure 1 for clarity reasons i.e. such that the washing chamber 2 is shown.
  • the dishwashing machine 1 further comprises a bottom surface 3 forming a lower limitation of the washing chamber 2.
  • the bottom surface 3 is provided with a circular opening 6 arranged roughly in the centre of the bottom surface 3.
  • Two side walls 11, a rear wall 12, a top surface 13, the door (not shown) and the bottom surface 3 limits the washing chamber 2 of the dishwashing machine 1.
  • the machine 1 further comprises a sump cup 4 for collecting and holding washing water.
  • the sump cup 4 being arranged below the bottom surface 3 in connection to the opening 6 such as to allow washing water to flow from the washing chamber 2 into the sump cup 4.
  • the sump cup 4 has in this example a cylindrical shape with a bottom and with inner walls forming a circumferential limitation.
  • An elongated filter member 8 adapted to be inserted through the opening 6 in the bottom surface 3 and elongate downwards into the sump cup 4 when attached at the opening 6, is removed from the sump cup 4 in Figure 1 .
  • a handle 14 on the filter member 8 facilitates the removal and insertion into the sump cup 4.
  • the bottom surface 3 is inclined downwards towards the opening 6 such as to facilitate that washing water flows towards and into the sump cup 4 during operation of the machine 1.
  • a flat sieve 10 that surrounds the opening 6 is arranged on a part of the bottom surface 3.
  • the bottom surface 3 of the washing chamber 2 also forms an upper limitation of a space 19 arranged below the washing chamber 2 in the washing machine 1.
  • the sump cup 4 extends downwardly from the opening 6 in the bottom surface 3 such that the cylindrical body of the sump cup 4 is essentially located in the space below the bottom surface 3.
  • the dishwashing machine 1 also comprises an arrangement for re-circulating washing water from the sump cup 4 back into the washing chamber 2 of the machine 1, the arrangement comprising pump means and flow ducts (not shown) connecting the sump cup 4 to the washing chamber 2.
  • the washing water is applied to the goods to be washed in the washing chamber 2 via spray arms (not shown).
  • Pump means, flow ducts and spray arms are generally well known as such to a person skilled in the art.
  • the space below the bottom surface 3 commonly accommodates the pump means.
  • FIG. 2 shows that a heating element 5 for heating re-circulating washing water is arranged in the sump cup 4.
  • the heating element 5 is formed of a pipe arranged in a coiled helical structure inside of which a substantially vertical cavity 7 is formed. Both ends of the cavity 7 is open.
  • the heating element 5 is positioned such that the vertical cavity 7 is open towards the opening 6 in the bottom surface 3 of the washing chamber 2, i.e. an upper open end of the cavity 7 faces the opening 6.
  • the heating element 5 is concentrically arranged in relation to the opening 6 so that the cavity 7 and the opening 6 are vertically aligned.
  • the coiled heating element 5 is arranged substantially along the inner wall of the sump cup 4.
  • the diameter of the coiled heating element 5 is adapted to the inner diameter of the sump cup 4 such that the vertical cavity 7 is formed in the centre of the sump cup 4 in which the heating element 5 is arranged.
  • the vertical cavity 7 is suitable for receiving the filter member 8 shown in Figure 1 .
  • Figure 3 illustrates the heat exchange taking place between the heating element 5 and the washing water flowing into the sump cup 4 from the washing chamber 2.
  • Cold water indicated by arrows 15, flows from the washing chamber 2 into the sump cup 4, and is heated as it passes the heating element 5 in the sump cup 4, thereby being heated before being passed on from the sump cup 4, indicated by arrow 16, to the re-circulation arrangement (not shown) via a recirculation outlet 9.
  • the ends of the coiled pipe forming the heating element 5 form an outlet and an inlet 5a, 5b (see figure 3 ) allowing the heating medium to enter and exit the heating element 5.
  • the outlet 5b and inlet 5a do not necessarily have to form true ends of the pipe since it is possible to extend the pipe and let it form a closed loop.
  • the ends 5a, 5b are arranged to extend downwards in an axial direction of the coil in parallel to each other.
  • These ends 5a, 5b are connected to pipes or tubes (not shown) for further connection to a heat source (not shown) for allowing heating of the heating medium intended to flow through the pipe forming the heating element 5.
  • a heat source not shown
  • the heating of the heating medium can be arranged in various ways.
  • Figure 4 shows a further view of the sump cup 4 in which the elongated filter member 8 is arranged.
  • the handle 14 extends out of the sump cup 4 such that the filter member 8 is graspable from inside the washing chamber 2.
  • the filter member 8 is configured to filter washing water that passes from the washing chamber 2 via the opening 6 in the bottom surface 3 into the sump cup 4.
  • the filter member is arranged such that it extends from the opening 6 in the bottom surface 3 into the sump cup 4, i.e. it protrudes in a downward direction into the vertical cavity of the coiled pipe.
  • a space is formed between the flat sieve 10 and the inclined bottom surface 3 that allows washing water to pass through the sieve 10 and flow towards the opening 6. Water flowing this way is thus filtered by the sieve 10.
  • the filter member 8 is centrally arranged in the sump cup 4 such that a ring-shaped entrance to the sum cup 4 is formed around the filter member 8 at the opening 6 and such that a tube-shaped space 17 is formed below the ring-shaped entrance in the sump cup 4 between the outer circumference of the filter member 8 and the inner walls of the sump cup 4.
  • the heating element 5 is arranged in this tube-shaped space 17. Washing water flowing through the sieve 10 may enter the tube-spaced space 17 via the ring-shaped entrance.
  • Figure 5 shows a cross-sectional view of the sump cup 4 with the filter member 8 arranged in place.
  • the tube-shaped space 17 between the outer circumference of the filter member 8 and the inner walls of the sump cup 4 is also shown in Figure 5 .
  • the heating element 5 is arranged in this tube-shaped space 17, thereby encircling the filter member 8. Washing water entering the tube-shaped space 17 will have passed either the flat sieve 10, if entering via the ring-shaped entrance around the filter member 8 at the opening 6, or the filter member 8, if entering via the centre of the vertical cavity of the coiled pipe 5. The washing water will therefore be filtered before coming into contact with the heating element 5.
  • the re-circulation outlet 9 is arranged in the wall of the sump cup 4 at a distance from the bottom.
  • the outlet 9 is fluidly connected to the arrangement for re-circulating washing water, the arrangement being located outside the perimeters of the sump cup 4.
  • the washing water is heated by the heating element 5 when passing the sump cup 4 prior to exiting the sump cup 4 via the outlet 9 onwards to the arrangement of flow ducts and pump means for re-circulation.
  • a drainage outlet 18 is arranged in the wall of the sump cup 4, adjacent the bottom, such that the sump cup 4 may be drained at the end of a washing operation.
  • the filter member 8 comprises in this case a coarse filter 8a and a fine filter 8b, seen in Figure 5 .
  • the fine filter 8b is arranged around the coarse filter 8a such that the fine filter 8b encloses the coarse filter 8a.
  • the handle 14 is arranged upon the coarse filter 8a.
  • the heating medium can be water or other medium commonly used in heat exchangers and/or heat pumps.
  • the heating element does not necessarily have to extend circumferentially in the sump cup to form a vertical cavity, or to form a coiled pipe structure.
  • Other shapes and structures are possible.
  • a heating element in general shaped as a tube or similar with a vertical cavity can be relatively large but allow the use of a relatively small sump cup and still allow a filter to be inserted into the sump cup. This allows for efficient heat transfer and filtering.
  • a pipe provides for a large heat exchange surface that enhances the heat exchange.
  • a pipe can be arranged in other patterns that, as a whole, forms a tube-shaped structure or similar, for instance by providing the pipe with a large number of bends, a coiled pipe structure is an effective way of providing the general shape.
